Use RequiredFiledValidator along with this RegularExpression validator

Hey Navaneeth
the problem here is we can't use asp validator for our application as after firing we are changing the style sheet of controls (in base control) by re rendering its content

I guess this can't be done on a single regular expression. Are you allowed to use a custom JS function, Then you can make use of two expressions and validate it.

Use Trim function and check the length. This will trim white spaces in the both end. You can add whitespace trimming in regular expression too. But I think it will remove the spaces in between the words (Sandeep Akhare)

It's very interesting. Download RegExBuddy. It's a ultimate tool, and it helped me a lot to learn regular expressions.

That's what i am doing finally
// Check for blank spaces In both first and last Name fields
if (String.IsNullOrEmpty(txtFirstName.Text.Trim()))
{
this.reqFirstName.IsValid = false;
}

reqFirstName is my validator derived from custom validator
this line of code i am writing in my Pages not in validator
then question will be why i have used this validator.
i think its not proper implementation of validator
Any way thanks for your suggestions and providing me RE tool

You can use target="_blank" to make a link fire a new window. You can't make the event from one page fire in another, ASP.NET does not work that way. You can write javascrpt to notice when a selected index is changed and call javascript in a child window, which could create a postback in that page, but you can't do it just by hooking up events in the framework.

Do you mean selectedIndexChanged event should be fired in new window from parent window?

Hi guys,

In my project I have to use a text area in which the description is entered. I want to restrict the users to use the html and script tags. I would like to allow the following tags bold , break , paragraph and underline. What is the coding that I have to use? If anybody knows the answer or have any suggestions , please reply.

Thanks
Jith

Use a regular expression validator to not allow any other tags. Then make sure you also write code in your code behind to strip any other tags that may exist, as validators can be bypassed by a determined user.

Hello all,

I want to change/modify value of particular column (GridView). I am processing that code in RowDataBound by writing e.row.cells(index).text = <processed value>. Its working fine.

Now my columns are dynamic few should be visible=true and few false. So problem here is i cannot have its index or i cannot predefine them.

I tried to convert e.row.dataitem to datarowview and tried to change its value but its readonly.

How can i do so?

Thank you in advanced.

You can set nowrap="nowrap" in <td tag

eg.

This is sample code testing for nowrap. This is sample code testing for nowrap. This is sample code testing for nowrap. This is sample code testing for nowrap. This is sample code testing for nowrap. This is sample code testing for nowrap.

You can also have same with div tag.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
